Question

eq51: diagnose the hearing loss for the patient below, including the frequencies.

Explanation:

Step1: Analyze the graph

The x - axis represents frequency (Hz) and the y - axis represents hearing level (dB). Normal hearing is around 0 - 20 dB.

Step2: Determine hearing loss at different frequencies

  • At 125 Hz: Hearing level is around 10 dB (normal).
  • At 250 Hz: Hearing level is around 10 dB (normal).
  • At 500 Hz: Hearing level is around 10 dB (normal).
  • At 750 Hz: Hearing level is around 20 dB (normal).
  • At 1000 Hz: Hearing level is around 25 dB (mild hearing loss).
  • At 2000 Hz: Hearing level is around 45 dB (moderate hearing loss).
  • At 3000 Hz: Hearing level is around 55 dB (moderate - severe hearing loss).
  • At 4000 Hz: Hearing level is around 60 dB (moderate - severe hearing loss).
  • At 6000 Hz: Hearing level is around 40 dB (moderate hearing loss).

Answer:

The patient has normal hearing at frequencies 125 Hz, 250 Hz, 500 Hz, 750 Hz. At 1000 Hz, there is mild hearing loss. At 2000 Hz and 6000 Hz, there is moderate hearing loss. At 3000 Hz and 4000 Hz, there is moderate - severe hearing loss.
